Lili NE-IORMING DEVICE FOR TYPE-WRITING MACHINES.

Application filed May 1, 1916, Serial No. 94,526.

To all whom it may concern:

Be it known that I, JAMES E. SIMPsoN', a citizen of the United States, and resident of the boroughof Brooklyn, in the county of Kings and State of New York, have i11- vented certain new and useful Improvements in Line-Forming Devices for Type \Vriting Machines, of which the following is a specification.

This invention relates to line forming devices for type-writing machines, and it has particular reference to means, attachable to machines of various makes, or forms ing a permanent part of the equipment thereof, whereby in the movement of the paper carriage longitudinal lines may be drawn,.and 1n the. revolving movement of 'the laten vertical lines may be drawn.

on the platen as occasion requires.

y improvements further contemplate, for the line producing medium, the employment of a self-inking wheel, or roller having anarrow periphery, which is supported near the platen, to normally not interfere p with the operation of the types; but to be movable into direct contact with the pgper aid self-inking roller or the like is adjustable into both horizonta-l and vertical positions, that it may be capable of drawing or ruling" either horizontal or vertlcal lines, and it is provided with detaining means, for holding it in either one of those set positions.

With these and other objects in View, my invention consists of a holder, capable of attachment to a type-writing machine, and having a line forming wheel pivoted therein. The arrangement is such that the peripheral edge of said wheel, which is narrow, to produce a line of suitable width, is

in opposed relation to the platen, near the printing point thereon, but spaced therefrom. Within said holder, at the rear 'of and in tcnsional contact with said wheel,

' is an inking pad which may be in the form of a. roller, to supply ink to said wheel in the rotation of the latter. Said inking, pad,

, may be removably supportedin said holder,

for purposes of replacement.

The holder may be loosely supported in. a suitable bearing, tobe capable of reciproeating movement, to and from the platen, and to enable the line forming wheel to move into either a horizontal or vertical position. The Wheel may be held normally inactive, as by a spring to retract the holder,

and detaining means, as a spring, may be Specification of Letters Patent.

provided to hold the wheel in a set position for producing either a horizontal line, or a vertical line.

Other features and advantages of, my said invention will hereinafter appear.

In the drawing:

Figure 1 is a side elevation, enlarged, of my improved device, shown in conjunction with portions of a. type-writing machine, and I Fig. 2 is a top plan View thereof, and

Fig. 3 is a similar View ot-a' modification.

Parts only of a type-writing machine, broken away, are shown in the views, in cluding the frame 1, platen 2, and a type bar 3, those portions however serving to illustrate the relative arrangement, with a type-writing machine, of my line forming device. Thus, a bracket 4: is here shown as attached to the front plate (for convenience) of a lloyal machine, said bracket comprising a bearing 5, in which a rod 6 is mounted to both revolve and reciprocate, an extending portion of said rod, at one side, having a push button 7, and ing portion at theothcr side, as 8, having squared surfaces 9. Between the bearing; 5 and push button 7 there may be a spring" 10,- tohold the rod normally extended that side; and means, as a, flat spring 11, secured at one end to the bracket, may bear Patented May 8, 1917.

an extendsionally staythe rod 6 in a set rotated position, for a purpose to be described hereinafter. Mofintcd upon the squared portion 9 is a holder for the line forming device. This holder may consist of an angle plate comprising the end portion '12 which is connected to the rod 5, and the side portion 13' which projects in the direction of the platen. Said portion 13, at its free end, may have a web 14, which carries a plate 15 that is parallel with portion 13, and, with said plate 13, provides bearings for a shaft 16, carrying wheel 17. Secured within the aforesaid holder, to end portion 12, is a s'pring 1 8, which is provided, atits free end, with a holder to form a pivotal bearing}, of an ink roller 20, which is mounted thereon, at the rear of wheel 17, and is pressed by said spring into ink imparting contact with said wheel. A plate 21 may be hinged to the holder portion 12, as at 22, that it may close, as a gate, into the position shown. in dotted lines in F ig. 2, vihere it is in parallel i I an adjustable strip 27, which is slidable in ism with holder portion 13, and may pro-' VldO a bearing for the end of pin 19; or said plate 21 may swing open to the position shown in full lines in Fig. 2, thereby permitting the ink roller, removed from pin 19 and the new one put in its place.

The wheel 17 may be of suitable cpnstructo be freely holder, and a tion, but i's'characterized by having a narrow peripheral edge, of desirable contact contour and width, whereby it may receive ink from the ink roller 20, and, in rolling over the paper, as the platen or paper support is moved to. and fro-or revolvedthereby impress upon the paper a clear and sharp ink line of any length. I

In the drawing the holder is shown in such rotated position that. .the wheel 17' is .presented vertically with relation to the platen, so that, upon applying inward pressure to the push button 7, to press the wheel against the platen, 3nd then by revolving the, p aten, a vertical line will be drawn upon the paper carried by the platen. If, instead,

a horizontal line is to be drawn, then the,

holder is given a quarter turn in its bearin 5, the spring 11 yielding in that act until it comes to rest upon the squared face 9 which represents the-other position for the wheel that in which the wheel is disposed horizon tally, to draw a horiaontal line. ,Then, upon appl ing the same pressure through push button 7 and movin the latch laterally, a horizontal line wil there y be produced.

Means, such as herein shown, may be employed for producing lines of different colors, as for example by the use of two line reducing wheels, each having a separate ink roller of different colors, both pairs of wheel and roller being carried by the same holder, and capable of alternating in their operative relation with the platen.

In Fig. 3 I have shown a holder 23, in which are independently mounted the ink markin wheels 24 and 25, foxdifferent colored in s; the wheel 24 having a fixed bearing in said holder, and deriving its ink feed from a roller- 26, which is supported in the" holder in a fixed position relatively to said wheel 2*; whereby said markin wheel 24 is'operable, with the holder'23, 1n the same manner as the device shown in' Figs. 1 and 2. r

i The holder 23, as stated, may also carry a second marking wheel 25-, mounted as onguides 28; said strip 27 having "a detent 29, ada ted to enter arecess or seat 30 in the hol er; although, in the drawing the recess or seat is shown as formed upon a spring piece carried by said holder; the purposeof said seat or recess bein to retain the strip 27 in a projected pos1tion in which 'the' wheel 25 is held .in operativecontact with the platen, or with a work sheet thereon. The strip 27 also carries an ink feed" roller 31, for the wheel 25, and in operative relation therewith; whereby, when said strip 27 is projected to adjust the wheel 24 beyond the position of the Wheel 24, said wheel-24 may thereby be brought into pressure contacting relation with the platen, to mark the Work sheet i'nthe' movement of the platen against said pressure.

Variations may be resorted to within the spirit and scope of my said invention, and

' parts thereof used without others.
